ELECTRIC ACCUMULATORS.
Professor Hannover, of Copenhagen University, has invented an apparatus by which it is possible to charge an accumulator with five times as much electric energy as any other existing accumlator of the same size. For instance, a train consisting of, say, 16 carriages, if it is to be lighted during a journey of seven hours, requires an extra carriage for accommodating the accumulators, which have to be recharged at the works before starting on another journey. By the new method the same accumulators would be charged at once with electricity which will last for thirty-six hours. The problem, for which patents have been lodged all over the world, has for many years baffled the greatest scientist-s. Professor Hannover has been able to manufacture a new metal, which he calls "pore metal," and this metal, owing to its porosity, develops more electricity and retains it longer than any metal hitherto known.
